WINDOW CLEANER 0R WIBER.

To all 107mm t may concern Be it known that l, HENRY M. HOWELL, a citizen of the United States, and a resident oit' Monroe, in the county ot' Ouachita and State oi? Louisiana, have invented certain new and useful Improvements in l/Vindow Cleaners or llipers, olf `which the following is a specification.

rllhe present invention relates to Window cleaners or Wipers'l` and has for its object to provide a device of this character Which is adapted to thoroughly and completely Wipe or clean the glass ol a Window, Wind-shield, locomotive-cab or the like, Which may be readily operated and requires itor its operation the exercise ot' a minimum degree oi effort and ot attention on part of they operator, and which is ot simple and durable construction,I reliable in operation, attractive in appcfuance and easy and inexpensive to manufacture and install.

Other objects and advantages ot the inventiou reside in certain novel features of construction, combination and arrangement oi parts which will be hereinafter more fully described and particularly pointed out in the appended claims. reference being had to the accompanying drawings forming part of this speciiication. and in which:

Figure 1 is a view in longitudinal vertical section of the invention organized with the Window;

Figure 2 is a horizontal line 2-2 of Figure 1;

Figure 3 is a fragmentary perspective vien7 of the bearing and adjacent instrumentalities oi the Wiper carrier;

Figure f1- is a fragmentary view in front elevation;

Figure 5 is a fragmentary sectional view ot a slightly modified form of the invention;

Figure 6 is a sectional view on line 6-6 of Figure 5;

Figure 7 is a detail view in elevation, illustrating the locking mechanism employed in conjunction with the modified form.

Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment of the invention, and especially to Figures 1 to 4, the numeral 10 designates the Window which consists of a pane of glass, or other suitable transparent material and which is mounted in any suitable manner in the frame 1l. A cleaning element or Wiper 12 is provided and prefersectional view on Specification of Letters Patent.

ably consists oi a strip of rubber or other material which extends entirely across the pane of glass and which is adapted to trav erse the pane by partaking of a bodily reciprocatory motion thereacross. The carrier 15 supports the Wiper and carries it through its movements and consists of a bar having` a longitudinal groove 15L in Which the Wiper is received and secured. At its end the 'carrier is reduced to provide arms 16 which extend through suitable slots 17 provided in bearings designated generally at 18. `These bearings 18 are arranged along each side of the Window and are suitably supported upon the frame of the Window .by `fastening means such as screws 19 or the like. They are identical in construction and .each includes an elongated guide 2O and an enclosed track 21 which runs parallel With the guide lor its'entire lengt-h. The track and the guide are separated from each other by means of a partition 22 having an opening 23 therein tor its entire length to establish communication between the guide and the track.

A guide block 24C is slidablyreceived in the guide QOIand is connected With the arm 16 of the carrier. Adjacent the groove 23 a ftrunnion 26 ext-ends from the guide block 24 through the groove and across the track 21. A roller 27 is mounted on the trunnion and'is operatively arranged on the track.

Means is-pro'vided for impartingmotion to said carrier to cause the wiper totraverse the glass and including a barrel 30 extending outwardly from the lower end of each of the bearings 18 and having a slot 31 extending of the upper portion thereof. The outer end of each barrel is closed, as at 32, and the inner end of the barrel extends through the bearing and through the frame 11 and is open at its inner end as at 33. A plunger is mounted for reciprocatory movement in said barrel and is provided at its outer end with a handle or hand grip 36 whereby it may be manually operated. The plungers are connected by means of a transverse bar 38 having a knob or other suitable hand grip provided centrally thereof. The bar 38 and the hand grip 39 may be utilized by the operator in lieu of the handles 36 whenever it is desired to do so.

Motion transmission means is provided ttor transmitting the motion of the plunger 35 to the carrier and preferably consists of Cil ra l

the link i0 pivotally connected, as at il to the plunger and pivotally connected as at 4t2 to the trunnion 26. As most clearly indicated inFigure l, as the plunger is reciprocated the end oi? the link pivotally connected to the trunnion 26 Will be constrained to inove upwardlyand downwardly and the guide'block 9A- andthe roller 27 highly adapt the organization to partake ot this niove ment as the guide block is freely slidable in` roller 27 is readily moin its guide and the The link 4.0 in partaking able on its track.

of its increment operates through the slot oi.

the barrel and in order Ato accommodate the link in its lovverinost movement, the plunger is provided With a tapered slot, as indicated in dotted lines at 30a in Figure l.

In the Inodiiiediorm shown in liigures 5, (3 and 7" the Wiper is constructed pretion 46.V The link here designated at 51 is disposed in bet-Ween therbarrel and its bearing. Locking mechanism is provided for retaining the barrel 1n collapsed position'and includes-a lock lug '5a carried by thebarrel v4&5 and cooperable with the spring latch member 55 carried by the bearing and having a head 56 engageable with the lock lug.

I claim:` t i i 1.1111 a device of the character described, a Wiper, a reciprocable carrier Vfor said Wiper, bearings for said carrier and; including a track and a guide,a roller on said carrier operatingV on said track, aguide block incassa on said carrier operating in said guide, means ttor imparting motion to said carrier `including a barrel having a slot, a reciprocablc plunger in said barrel, and a link operating through said slot and connecting said plunger and said carrier, and operating mechanism including a knob connected with said glunger.

2. In a device oi the character described, a Wiper, a reciprocable carrier for said Wiper, bearings for said 'carrier and including atrack and a guide, a roller on said carrier operating on said track, a guide block on said carrier operatingiin said guide, and means for imparting motion to said carrier including a barrelhaving a slot,v a reciprocable plunger infsaid barrel and a link operating through said slot and connecting said plunger and said carrier.

3. In a device of the character described, wiper, a carrier for said Wiper, bearings ttor said carrier, ineans for imparting motion to said carrier including a pivoted barrel and a plunger in said barrel consisting ot pivoted sections, a link connecting said Aplunand said carrier, and operating nieans ior said plunger.
